Flexible and Flex-Rigid

Flexible and Flex-Rigid Printed Circuit Boards.

Flexible and flex-rigid printed circuit boards, unlike rigid PCBs, can bend, twist and fold.

They are intended for dynamic applications, as an electro-mechanical connection element between electronic parts called upon to bend hundreds of thousands of times. They can also be used in static applications, where several rigid portions of a single flex-rigid PCB are connected together by flexible parts, to maximise the number of electronic components in restricted spaces.

It is difficult to solder components and achieve a large number of interconnections on simple flexible products. One solution is to use a stiffener. Part of the circuit becomes rigid, to facilitate additions and soldering on components while increasing the number of interconnections.
However, a stiffener is not usually part of a printed circuit board. In flex-rigid PCBs, on the other hand, the rigid parts are also part of the circuit board.

In recent years the use of flexible and flex-rigid PCBs has grown exponentially because the benefits have been understood, including:

  • the possibility of reducing the necessary space thanks to the 3D “architecture”
  • avoiding the use of wiring and connection connectors between different PCBs and, therefore,
  • being able to have a single printed circuit board to manage and test
  • minimising the risk inherent to soldering and
  • reducing assembly costs

Positive effects deriving from the use of flex-rigid PCBs also include:

  • increased reliability and weight reduction
  • increased signal integrity
  • reduction in the loss of signal to the connectors. Moreover, flex-rigid printed circuit boards can also be made
  • with mixed materials for RF applications and
  • with HDI construction.

We are among the leading manufacturers of flex-rigid PCBs.
Our expertise and technological know-how allow us to offer you flex-rigid PCBs with stack-ups of any architecture and up to 12 flexible layers.
